I've got a 6br,6x284 and 6mmremAI and my next project will be a 6x250. I used to shoot a 6HLS with a 1/14 twist just a different version of the 6x250 and was a pretty nice round. Might want to check with Kirby but think may be alittle on the light side as an antelope rifle alot depends bullets and range. I'll find out in another week if I get drawn for antelope and if so will use a 6.5x284. Well good luck.

One of my most favorite long range rounds hands down is the fast twist 6br improved. Performance way beyond the sum of it's parts. This is a pic of one of my latest 1000 yard gong groups. It was shot with 95 grain Berger VLD's at 3030 fps using 31.5 grains of Varget with an sd of 4 fps! The gong is a 9" circle, and the group goes exactly 5"(outside to outside) for the 5 shots. The fifth shot is actually exactly inside the upper right splash (thus leaving a heavier,darker mark) made by the 2nd shot. The bottom edge hit is a .338 300 grain MK from my favorite 2k round, the .338 MOAG. The 6br improved fast twist will typically always shoot this well if I do my part reading the wind flags. Best of all, I can shoot up to 20 rounds on an 80 degree day without toasting my barrel's throat.
